Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25588, here are decompositions:

  • 5 + 25583 = 25588
  • 11 + 25577 = 25588
  • 47 + 25541 = 25588
  • 131 + 25457 = 25588
  • 149 + 25439 = 25588
  • 179 + 25409 = 25588
  • 197 + 25391 = 25588
  • 239 + 25349 = 25588

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25588 first appears in π at position 137,176 of the decimal expansion (the 137,176ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
